Look for the doc titled "New Features".
I'm not aware of anything that will "break" your code... just enhancements.
Things to note: Flashback Data Archive is now part of EE for 188.8.131.52. Previously, it was licensed add-on.
So, if you need to keep the history of changes done to a table.... piece of cake; no triggers needed.
I grew up in Reading Penna. - not far from Kutztown, Penna. (PA) Thanks for responding.
I thought there was something in 184.108.40.206 with SQL date types that changed.
The 4 in 220.127.116.11 is a Component specific release number (or patch set release). I will assume that is component architecture and not code stuff. I am using hibernate and some hardcoded sql queries.
